The only defense most have to my argument is a fallacy. That supposedly the 60s (or 90s) had more racism or bigotry and therefore Roddenberry's vision of a better future is tainted. That's a ludicrously wrong argument for the simple reason that Roddenberry didn't die in the 60s and he envisioned TNG and even if the 60s (or 90s) culture had more racism the intention was still hopeful and at the end of the day and most importantly even if the culture of the 60s (or 90s) had more bigotry the intention of the vision was clearly there since compared to the rest of the culture of the real world at the time it was an extremely improved society.
I'm not so sure I see "most" people saying that. I do see a lot of people saying that bleached, homogenized, perfected societies and/or people that many fans seem to think define Roddenberry's Vision are
1. Not actually what Star Trek is about
2. A load of steaming iguana feces
